Re: [fxtf-drafts] [css-masking] Add mask-position-{x,y}

The Working Group just discussed `[css-masking] Add mask-position-{x,y}`, and agreed to the following resolutions:

* `RESOLVED: create an ED for Masking L2?`
* `RESOLVED: put mask-position-x/y into that draft`

<details><summary>The full IRC log of that discussion</summary>
&lt;dael> topic: [css-masking] Add mask-position-{x,y}<br>
&lt;dael> github:<br>
&lt;dael> krit: One prop atm. There was a proposal to add -x and -y. It's in webkit, I believe. Request was to spec. We agreed to algn as much as possible to background spec. If background won't do position-x and -y then mask won't. Same for mask-repeat.<br>
&lt;dael> fantasai: Background-position-x and -y is in L4 which isn't fpwd but it was resolved to add.<br>
&lt;dael> krit: and repeat?<br>
&lt;dael> fantasai: I don't think so.<br>
&lt;dael> krit: Then since this is CR it's prob. best not to add yet.<br>
&lt;Chris> agree, better not to add them *yet*<br>
&lt;dael> fantasai: I think we had a discussion about repeat and we weren't going to add unless required for compat since there wasn't a use case.<br>
&lt;Chris> yeah it is more alignment between masking and backgrounds<br>
&lt;dael> krit: My concern isn't them having it, but how we handle for masking spec. Since the spec is in CR I don't want to add features that aren't in L4.<br>
&lt;dael> fantasai: I would agree. Adding mask-position-x and -y to L2 might make sense. L1 should stay.<br>
&lt;dael> krit: We don't have a L2 yet. Should we wait or create the L2 already and put the properties in there?<br>
&lt;dael> astearns: I have a question about background-position-x/y. Have blink and webkit already impl it?<br>
&lt;dael> krit: as far as I know yes.  For mask it was a webkit prefix.<br>
&lt;dael> astearns: Right.<br>
&lt;dael> astearns: For myself I would like to have a next level of masking with these features since mask-position-x/y is in a couple engines and maybe a third.<br>
&lt;dael> krit: THen we need to resolve to have level 2 and then move it.<br>
&lt;dael> astearns: I think first step is have a resolution to put it into the next level. Once an ED has these features we can have another call.<br>
&lt;Chris> +1 to ED<br>
&lt;dael> krit: I wasn't asking for fpwd, just an ED for L2.<br>
&lt;AmeliaBR> +1 to having a level 2 of Masking<br>
&lt;dael> astearns: Fair.<br>
&lt;dael> astearns: Any objections to creating an ED for Masking L2?<br>
&lt;dael> RESOLVED: create an ED for Masking L2?<br>
&lt;dael> astearns: Obj to putting mask-position-x/y into that draft?<br>
&lt;dael> RESOLVED: put mask-position-x/y into that draft<br>
